MARCUS B. BEHRMAN, OF BROOKLYN, NEW YORK, A .SSIGNOR TO THE LOX SEAL CORSElOR'llN,v 0F II.\TOITR,'JI'HA BERGEN, NEW JERSEY, A CORPORATION OF NEW SAFETY RAZOR.

Application led June 1, 1321. Serial No. 474,095.

particularly to combination razor and stropplng devices. The principal object of the invention is the provision of an improved simple and eifectiveddevice of this character,-

which is particularly`- adapted for use with thin flexible blades, suoh as the well known blades having cutting edges at both sides, in which the blade is adjusted into shaving position by flexing or clamping its edge or edges over and against a guard or guards.

This is accompllshed by mounting the blade on a movable member, so positioned in relation to the frame as to permit the insertion of a strop between the two, the blade moving from one stroppin position to another when the direction'o stropping is reversed; and providing a member which is readily adjusted into position to hold the movable member stationary and i'lex 'or clamp the edge or edges ofthe blade in shaving position, when the device is to be used for shavinv.

@ther objects of the invention comprise the provision of improved forms of construction` and combinations of parts. all as will be more fully explained hereinafter in the following specification and particularly pointed out in the appended claims.

ln order that a clearer understanding of the invention may be had, attention is hereby directed to the accompanying drawings forming part of this app ication and illustrating certain embodiments of the lnvention.

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1;

Fig. 3 is an end elevationof the construcltion shown in Fig. 1, the handle being broken away;

Fig. 4 is a top plan view of the same; Figs'. 5 and 6 represent vertical sections taken on line 5-5 of Fig. 4 with the top blade clamping member removed and astro p inserted through the device; Fig. 5 representing stropping of the blade in one direct1on andF ig. 6 in the opposite direction;

F 1g. 7 is an enlarged side elevation of the parts of the device separated 4from each other, the blade retaining means being shown in open position;

F 1g. 8 is a top lan view of portions of the device located) beneath lines 8-8 in F ig. 7

Fig. 9 is an end elevation of a modified form of device; and

ig. 10 is a side elevation of the form of devlce shown in Fig. 9. L

Referring to the drawings, the frame of the device comprises a. member 1 which may be formed of sheet metal pressed into the f orm o f an inverted arch. in transverse section, with its side edges bent outwardly and downwardly, portions of these side edges belng out away to form guards or combs 2, 2. A handle m'ember 3 is secured in any desired manner to the bottom of frame member 1 at the center thereof to extend downwardly therefrom, frame member 1 and handle member 3 having a vertical opening 4 eX- tending therethrough.

The razor blade 5 is su ported on a movable menrber whereby t e blade may be moved from one position to another in stropping the same, to present different edge surfaces to the strop.' In the construction -shown in Figs. 1 to 8 of the drawings frame l is provided at i-ts ends with upwardly turned ears 6, 6, having aligned openings therethrough. These openings preferably take the form of vertical slots 61. The blade supporting member 7 is provided at its ends with downwardly extending lugsl 8 having cylindrical pins 9 extending outwardly therefrom, these pins being rotatively supported in the openings or slots 61 in ears 6 of the frame. Blade supporting member T has a central vertical opening 10 therethrough which is aligned with the opening 4 through the handle member 3 when member 7 is in its vertical position. Member 7 also. in the form of construction shown in the drawings. is provided with vertical openings 11, 11, therethrough, one at each side of the central opening 10. Member 7 is provided with short annular upward extensions .12, 12, surrounding openings 11, integral K with, or secured to, member 7. In the form of construction shown in 'Fig'. 2 member 7 may conveniently be made by a die casting process with extensions 12 and all other projecting parts integral therewith.

When blade 5 is a thin flexible blade of the well known form having cutting edges on opposite sides and three aligned openings through the blade, it may be positioned on member 7 by placing the blade on the member in such manner that upward l bar 13 which is hingedly connected at one end by pin 14 to a lug 15 extending upwardly from the end of member 7. Bar 13 is provided with openings 16, 17, 17, which are adapted to align with openingsv 10, 11, 11, when bar 13 rests in its horizontal, or closed position, in which the upward extensions 12 of member 7 preferably extend into openings 17, 17, of bar- 13.

Bar 13l may be latched in itsu operative position by any suitable means, such as a latch bar 1 8 hin edly connected togthe end of bar 13 opposite rom that at which ivot pin 14 is mounted. Supporting mem er 7 lis provided with an outwardly extending luggV 19 at its end opposite to that at which lug l5 is located, and latch bar 18 has an opening 20 therethroughinto which lug 19 will extend when the latch bar is swung downwardly into thev position shown in Figs. 3 and 10, lug 19 wedging within the opening, between the upper and the lower edges thereof.

When a blade is thus mounted on the blade support the latter may be oscillated through a short arc from one 'side to the other of the vertical position of member 7. Member 7 and bar 13 are each of less width Kthanvthe blade 5 secured therebetween, so

thatwhen member 7 is -,in its verticalxor interme'diate sposition the two edge portions of the blade Vwill extend laterally beyond members 7 and 13 above the two guards or combs 2, 2. In this position the' edges. of

ythe'blade will be separated vertically from' the guards-2, 2, by a distance sutlicient .to enable the msertionof astrop between the same. Insertion of the strop is facilitated when `.vertical slots 61 are used.

.through t e device,xthe strop causing Member 7 is preferably ven a somewhat V-shape, as shown, or is ot erwise provided with-a surface which will be enga ed fric-` tionally b astrop when the. latter 1s passed pivot `n. Fig.

device, above the guards- 2 and beneath I .65

member 7, member 7 extending downwardly pins 9 turning in the upper part of slots 61, and the rear edge of blade 5 pressed against the strop above one of the ards 2. When the razor is then moved 1n the opposite direction, as is shown in Fig. 6, member 7 will immediately be swung inthe opposite direction by engagement with the strop, so as to strop the opposite edge of the blade.

When the device is to be used as a razor a top clamping member 22 is mounted in position. In the form of construction illustrated this comprises a'rigid plate arched in its transverse direction, having lugs 23, 23, adapted to enter openings 17 in bar 13, and to pass downwardly through the upward annular extensions 12 of member 7 which are positioned within openings 17 and the openings in the razor blade through which extensions 12 pass. Member 22 is also provided with a downwardly extending centrally located pin 24' which 'is adapted to pass through opening 16 in member 13, the aligned opening 10 in member 7 and the central lopening of the blade, and to enter the opening 4 in frame 1 and handle member 1 The passage of the pin 24 through these aligned openings will immediately have the effect of securing member 7 in its vertical position. Member 22 is then adjusted into position to press theedge portions of the blade against guards 2 in shaving position.

In the form of construction illustrated a 'cylindrical member 425 extendsv upwardly by rotatingfjl member 25 about the pin 24,

member 25 preferably being provided with aknurledknob 2,9 at its lower end.

Member 22 is arched to extend over member 13 so that its edge portions-30, will press against the up er .edge portions of blade 5.

Accordingl w enthe member 22 is screwed down i't will flex the blade. and press its edge portions down against the upper surfaces ofA guards 2 intov shaving position.

. .....ttmiiumuulilll The closeness of shaving desired may, of course, be adjusted by tightening member 22 more or less, as is well known.

In the preferred form of construction member 25 is permanently mounted within the shell portion 31 of handle member 3. This may be arranged by providing'member 25 with a peripheral bead 32 a short distance above knob 29 and bending the lower edge 33' of shell 31 inwardly beneath bead 32, as is shown in Fig. 1. 4

The form 0fv construction illustrated in Figs. 9 and 10 is similar to that previously described, but differs therefrom in that frame member 1 is provided at its .ends with downwardly extendlng lugs 61 having openings therethrough, member 7 having downwardly extending arms or flanges 81 at its ends, pins 34 "extendingl through aligned openings in the lower portions of arms 81 and through lugs 61, to form the pivots for member 7 It 'will be noted that the provision of vertical slots 61 in ears 6, in the construction shown in Figs. 1 to 8 of the drawings, en-

lables pivot pins 9 to rise from the bottom of the slotswhen a strop is inserted, so as to give more clearance for the strop. This enables strops of different thickness-to be used, and also makes the device work better 'f a ,wider swing towards and away from the strop. When the device is used as a razor `Apins 9 will rest rmly on the bottom of slots 61, in which position the edges of the blade may be as close as is desired to the guards, so that knob 29 need only be turned a few turns to flex the blade edges down against the guards.

I consider that my invention is one of broad scope, not limited to the particular forms of construction which have been particularly described, by way of illustration but not of limitation. Stropping devices per se somewhat similar to those described herein 'are known, and means for clamping a blade vin a razor, similar to those described herein, are known; but I believe it to be broadly new to position a blade holder above the guards so that the blade may be stropped in situ, and to provide means for flexing the blade edges into shaving position against the guards. Other features of the invention are also thought to be of considerable scope,
